Magnetic resonance imaging (MRI) is a unique and versatile medical imaging diagnostic tool. Using MRI, physicians obtain highly refined images of the body’s interior. Strong magnetic fields and pulses of radio waves manipulate the body’s natural magnetic, producing images not possible with other diagnostic imaging methods.
Of body and mind, and deep meditation – Chinese data unraveled at University of Oregon show a training technique has brain, physiological linkage. – Chinese researchers have unlocked the mechanism of an emerging mind-body technique that produces measurable changes in attention and stress reduction in just five days of practice.
Bone marrow cell therapy may be beneficial for patients with ischemic heart disease – The injection of bone marrow cells into the heart of patients with chronic myocardial ischemia (reduced blood flow to some areas of the heart) was associated with modest improvements in blood flow and function of the left ventricle, according to a study in the May 20 issue of JAMA.
How to build a bigger brain – Study shows that meditation may increase gray matter. – Push-ups, crunches, gyms, personal trainers – people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?
Imaging study finds evidence of brain abnormalities in toddlers with autism – Toddlers with autism appear more likely to have an enlarged amygdala, a brain area associated with numerous functions, including the processing of faces and emotion, according to a report in the May issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Mother-daughter breast density study points way to earlier cancer risk assessment – A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that percent of breast water could be linked to the risk of breast cancer in middle age and older.
AUA counters mainstream recommendations with new best practice statement on PSA testing. New guidance stresses that PSA testing should be individualized, men should get baseline reading at age 40. – The American Urological Association (AUA) issued new clinical guidance ? which directly contrasts recent recommendations issued by other major groups ? about prostate cancer screening, asserting that the prostate-specific antigen (PSA) test should be offered to well-informed, men aged 40 years or older who have a life expectancy of at least 10 years.
University of Leicester team examine potential of new nano technology to pave way for development of a combined diagnosis/therapeutic strategy for cancer. – A multi-disciplinary team of scientists from the University of Leicester could be potentially paving the way for the development of a powerful new strategy for both the early diagnosis and treatment of prostate cancer.
Lack of strategies to manage MRI wait lists a key reason for excessive wait times – A new study headed by Dr. Tom Feasby, Dean of UCalgary’s Faculty of Medicine, shows that while Canada lags behind other countries in the number of diagnostic imaging devices, more machines are not the only solution to long wait times.
Functional abnormalities within a neural system subserves self-regulatory control, which may contribute to binge eating and other impulsive behaviors in women with Bulimia nervosa (BN). – Women with bulimia nervosa appear to respond more impulsively during psychological testing than those without eating disorders, and brain scans show differences in areas responsible for regulating behavior, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.
Research by Rice psychologist identifies area of brain key to choosing words – New research by a Rice University psychologist clearly identifies the parts of the brain involved in the process of choosing appropriate words during speech.
Ginkgo biloba does not reduce dementia or Alzheimer’s disease risk according to Pitt-led study in JAMA. – The medicinal herb Ginkgo biloba does not reduce the risk of dementia or Alzheimer’s disease development in either the healthy elderly or those with mild cognitive impairment, according to a large multicenter trial led by researchers at the University of Pittsburgh School of Medicine.
Researchers are developing a new screening MRI imaging technique for cervical cancer that would be more effective at spotting tumours early. – Using high-resolution magnetic resonance imaging (MRI) with a special vaginal coil, a technique to measure the movement of water within tissue, researchers may be able to identify cervical cancer in its early stages, according to a new study being published in the November issue of Radiology.
